Application filed. March 7, 1918.

To all whom it may concern Be it known that I, JOHN W. Cosenovn, acitizen of the United States, residing at Medford, in the county ofMiddleseX and State of Massachusetts, haveinvented certain Improvementsin cementing-Machines, of which the following description, in connectionwith the accompanying drawings, is a specification like referencecharacters on the drawings indicating like parts in the sev eralfigures.

This invention relates to apparatus for cementing sheet material andparticularly to that adapted for applying cement along the edges of thematerial.

An object of the invention is to arrange such an apparatus to operateupon adjacent or intersecting edges of work carrying a row of spacedprojections. To attain this object I provide a novel work :supporthaving spaces designed to allow the successivepassage of the projectionsin a series or the passage of a plurality of said projectionssinnrltaneously. For this purpose I may employ a plurality ofsupportsseparated from one another so as to receive readily the row ofprojections as an edge of the work is operated upon, one of the supportshaving a space which cooperates with that between the supports to admittherewith two projetl tions when the work is turned to operate onanother edge. 1

Another object of the invention is to insure the application of cementtoone face only of the work, avoiding the doubling over of the uncemented'side of thematerial into contact with the cement-applying means. To thisend my improved appara tus includes novel fold-preventing meanscooperating with the work adjacent to the applying means. As hereindisclosed, this fold-preventing means consists of scraping memberscontacting with the work, preferably on opposite sides, and, since thedonbling of the material is usually caused by its pressure against thegage which determines its position with relation to the applying means,I have shown the scrapers mounted on the work-engaging; face of thegage.

@ne embodiment of the invention is illus trated in the accompanyingdrawing, in whiclr,- t Figure l is a perspective view ofmy improvedcementing apparatus; 1

through the axes of the applying and supporting rolls;

Fig. 3 is a detail in perspective showing the rear of the work support,and

Fig. 4 is a similar view of the gage with its fold-preventing means.

The general construction of the apparatus is similar to that disclosedin my Patent No. 1,242,925, dated Oct. 16, 1917. This includes a frame10 at the top of which is mounted a tank 12 delivering, under thecontrolof thevalve 16,to a rotatable cementapplying roll 14.. Fulcrulnedat 18 upon the frame, and extending beneath the applying roll, is alever 19 forced normally upward by a spring not here shown, since it isarranged similarly to that in the above-mentioned patent. Upon the outerextremity of the lever an arm 20 is pivoted at 22, being held in normalalinement with the lever by a pin 24: but when the pin is removed beingcapable of being swung down to enable the parts carried to be cleaned:At the outer end of the arm is an upwardly extending portion 26, hereshown as integral, in which is a bearing for the spindle 28' of awork-sup porting roll 30 which is situated below the inner edge of theapplying roll 1d. Separated from the roll by a space at 32 is a secondsupporting member 3%, appearing as a vertical bar, secured to the sideof the arm 20 by a screw 86 and having an upper work engaging surface38, which may be curved so that it has the same contour as a portion ofthe periphery of the roll 30. The screw 36 preferably passes through avertical slot in the bar, by means of which connection the supportingmember 34; may be adjusted toward and from the applying roll 14. Thisallows the support tobetter present the work to the applying roll whensaid work is of different thicknesses across the area to be cemented.Theworkengaging surface 38 is slotted at 40, the widthof this slot beingsubstantially equal to that of the space 32, each being adapted topermit the passage of a projection carried by the work and beingseparated from one another by a distance equal to the spacing of theprojections. This slot dfildivides the support 34 into two er; tions 42and 44, the former being situated below the outer edge of thecement-applying roll while the portion 4'49 is midway betweenitseompanion and the roll 3Q. If workYin di-cated W" and consisting; forsample,

of a shoe upper which has such a row of projections as lacing hooks toextending along the inner edge, is to be cemented along said edge andits top edge for securing the lining prior to stitching, it may first bein troduced between the applying roll 14: and the support, with the rowof hooks in alinement with the space 82. As the work is advanced betweenthe support and applying roll, the roll 30 and portions 42 and M holdthe surface to be cemented into effective contact with the periphery ofthe applying roll, the space 32 allowing the hooks to pass throughwithout interference, one after another. When the upper is turned tocement across the top, the first of the series of hooks enters the space3:2 while the second passes through the slot 40. Here also, interferencewith the projections is avoided, while practica-lly the entire surfaceto be cemented is forced uniformly against the applying roll.

To guide work by contact with its edge so that the area cemented may beuniform in width, a gage is provided. This is here illustrated asconsisting of a block 46 having an inner reduced portion 48, the facesof which are curved similarly to the peripheries of the applying andsupporting rolls so the gage may be brought into close proximity withthem. From one side of the lower portion of the block extends an arm bywhich the gage may be secured to the lever 19, this being by means of ascrew 52 passing through a horizontal slot in the arm, allowing the gageto be adjusted to vary the width of the area cemented. It is found thatin coating some types of material which are thin and flimsy, contact ofthe edge of the work with the vertical guiding surface 5a of the gagecauses the mate rial to be doubled over, so that the wrong side ispresented to the applying roll and the work defaced. To avoid this,fold-preventing means is placed adjacent to the applying roll, itpreferably consisting of members 56, 56 mounted upon the surface 5-Clofthe gage for scraping over opposite sides of the work. These members Ihave shown as of thin resilient material mounted on studs 58, 58extending through horizontal bores in the block 456, these studs beingthreaded at the inner side of the block to receive nuts 60 for clampingthe members 56 against the face 54;. The members 56, 56 converge fromthe supporting studs toward a point near the reduced extremity of thegage, forming an acute angle with one another. At their adjacentextremities they are bent until they approach at 62 in substantially astraight line, bemg there approximately at right angles to the surfaceof the work. Said work 1s readily introduced into the tapered throatformed by the converging members, which yield from one another to permitthis, and drawn between the ends 62 into engagement with the applyingroll and support. As it is fed along by the rotation of the applyingroll the ends of the members 56 drag over the edge close to the gage,and if the pressure against the surface 51- tends to fold this edge uponitself, this is immediately straightened by the members. Their action inthis respect is more effective because of the direct approach of theends, it being found that if they are inclined throughout their lengthat the angle of their body portions there is a tendency to catch thefold between them, so that it is pressed down and held rather thanremoved. With the ends formed as herein described, it is practicallyimpossible for a doubled portion to enter between the members. Toprovide for the proper cooperation with work of different thicknessesand the tension under which the engaging ends 62 are forced against itby the resilience of the members 56, the angular relation of saidmembers may be changed by loosening the nuts 60, turning the studs tothe desired positions and reclamping them.
